Who You Are:

• You’ve built scalable, production-ready APIs in fast-paced environments, and are comfortable with the challenges that come with a growing startup.
• You understand event-driven architectures and have hands-on experience building real-time applications.
• You are fully capable of taking ownership of backend systems, from designing the database schema to writing efficient, maintainable code.
• You think beyond the code: optimizing performance, scalability, and security are as important as building new features.
• You’re comfortable troubleshooting complex issues, whether that’s API bottlenecks, database performance, or production issues.

Responsibilities:

• Design, implement, and manage a NestJS backend with a modular, scalable architecture that can easily handle real-time events and communication.
• Develop and maintain WebSocket services for real-time event-driven updates and ensure seamless communication across the system.
• Integrate RabbitMQ for reliable internal messaging, handling queues and ensuring event-driven workflows are efficient and fault-tolerant.
• Implement database management strategies using MongoDB, Redis, and Elasticsearch, ensuring efficient data handling, indexing, and optimization.
• Integrate with external APIs (JSON-RPC, XML-RPC, REST) to enhance system capabilities.
• Ensure high performance of the system by optimizing database queries, implementing caching strategies using Redis, and ensuring optimal indexing and data flow.
• Implement role-based authentication and authorization mechanisms using JWT, OAuth, and RBAC patterns within NestJS.
• Follow security best practices to ensure sensitive data is protected, credentials are stored securely, and the system is resilient to common vulnerabilities.
• Work collaboratively with cross-functional teams to ensure seamless integration between different services and technologies.

Must-Have Skills:

• Strong proficiency in Node.js and NestJS with TypeScript.
• Solid experience with MongoDB, Redis, and Elasticsearch for data storage and real-time data handling.
• In-depth knowledge of WebSockets and Socket.IO in NestJS Gateways, enabling real-time communication and updates.
• Experience with RabbitMQ for message queuing and asynchronous task handling.
• Strong understanding of authentication & authorization systems using JWT, OAuth, and RBAC (Role-Based Access Control).
• Expertise in optimizing APIs, including techniques for caching, improving database performance, and reducing latency.
• Familiar with API security best practices, including secure storage of credentials, encryption, and safeguarding sensitive data.

Key Skills:

• TypeScript, NestJS, WebSockets, Socket.io
• Redis, MongoDB, Elasticsearch, RabbitMQ
• API Optimization, JWT, OAuth, RBAC
